The document discusses several topics related to global warming and climate change:
1) Climate change has occurred naturally over the past million years, with temperatures varying by 0.5 degrees Celsius, but small changes can have large impacts.
2) The greenhouse effect is necessary for life on Earth and has existed as long as the atmosphere, trapping heat and maintaining temperatures around 33 degrees Celsius warmer than they would be otherwise.
3) The "grasshopper effect" describes how pollutants move from warmer to colder regions, tending to accumulate in polar regions where there is less evaporation.
The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions.
This is the presentation of Green House Effect. I made it for my university presentation. It works naturally. I'm going to be 1st of this presentation. Take care. Have a good Day.

Study: The Future of VR, AR and Self-Driving CarsLinkedIn
We asked LinkedIn members worldwide about their levels of interest in the latest wave of technology: whether they’re using wearables, and whether they intend to buy self-driving cars and VR headsets as they become available. We asked them too about their attitudes to technology and to the growing role of Artificial Intelligence (AI) in the devices that they use. The answers were fascinating – and in many cases, surprising.
This SlideShare explores the full results of this study, including detailed market-by-market breakdowns of intention levels for each technology – and how attitudes change with age, location and seniority level. If you’re marketing a tech brand – or planning to use VR and wearables to reach a professional audience – then these are insights you won’t want to miss.

Artificial intelligence (AI) is everywhere, promising self-driving cars, medical breakthroughs, and new ways of working. But how do you separate hype from reality? How can your company apply AI to solve real business problems?
Here’s what AI learnings your business should keep in mind for 2017.
Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.
2. Climate Change: Historically Not a “new” concept Scientists have determined that the earths temperatures have had a wide range for the last million years Last Ice Age roughly 100 000 years ago ( Canada was covered in glaciers) Range of + or – 0.5 degrees Celsius (although small) can have a large impact Climate change has had drastic effects at the poles (grasshopper effect) http://topics.nytimes.com/top/news/science/topics/globalwarming/index.html
3. Climate Change: The Greenhouse Effect Necessary for life on earth Has existed for as long as the earth has had an atmosphere Without the greenhouse effect the earths temperature would be 33 degrees Celsius colder (more like -19 C) Greenhouse Gases (GHGs)- metaphor refers to the earths atmospheres ability/ reliance to hold onto heat
4. The Grasshopper Effect A global issue in which POPs move from warmer to colder regions. The pollutants evaporate, travel through the atmosphere (on air currents), and then condense in a new location. Tend to stay in colder regions because there is less evaporation in those areas.
5. The Grasshopper Effect Less Evaporation Colder Polar Regions Temperate Regions More Evaporation Hotter Equatorial Regions
6. The Ozone Layer Forms the stratosphere and protects us from the suns UV Radiation Human activities are upsetting the balance of this gas In 1983 it was confirmed that there was a whole in ozone (over Antarctica) In 1998 the hole measured 26 million Km’s (roughly the size of Australia) How is it being destroyed? Chloroflouorocarbons (CFCs)- once they rise into the stratosphere, they become exposed to UV radiation and release chlorine atoms A single chlorine atom can destroy thousands of molecules of ozone
